Interesting. Apparently, most (if not all) FAA inspectors have never read case law. I was involved with straightening out some paperwork on several experimental aircraft some years ago, specifically with regard to several major changes that had been done and not properly documented. In all these cases, the FAA said "put it back the way it was when it was tested and you're good to go". As long as the FAA was happy, we were all happy!
